A vertical pipeline sand blaster with retractable device

Abstract

The invention relates to the technical field of a sand blower, and discloses a vertical pipeline sand blower with a retracting device; the vertical pipeline sand blower comprises a fixing device, thebottom of the fixing device is in contact with a pipeline, a supporting plate is fixedly installed at the top of the fixing device; a bearing I is fixedly installed at the side of the supporting plate; a rotating shaft is fixedly sleeved in the bearing I; and one end of the rotating shaft extending to the front face of the supporting plate is fixedly sleeved with a hand wheel. According to the vertical pipeline sand blower with the retracting device, through the mutual cooperation of the fixing plate, extruding plates and a screw rod, springs are in a relaxed state when the springs are at rest; the four extruding plates are extruded into the pipeline until the top of the pipeline is in contact with the bottom of the fixing plate; at this time, the spring is in a compressed state, and thespring force of the four springs remain the position of the fixing plate at the center of the pipeline, and the position of the fixing plate is fixed by a nut and the screw rod to prevent swaying during cleaning; and the stability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of sandblasting devices, in particular to a vertical pipeline sandblasting device with a retractable device. Background technique [0002] The sand blaster uses compressed air to transport powdery granular materials from one place to another in the pipeline, and during the process of converting kinetic energy into potential energy, the high-speed moving sand particles scour the surface of the object to improve the surface quality of the object. . [0003] The existing pipeline sandblasting machine is to place the pipeline horizontally, and then use the sandblasting machine to perform sandblasting on the inner wall of the pipeline, so as to remove rust and other impurities on the inner wall of the pipeline. This method can only clean the horizontally placed pipeline. However, many existing pipelines are installed vertically and are not easy to disassemble, so once the inner wall of these vertical pipelines i...

[0003] The existing pipeline sandblasting machine is to place the pipeline horizontally, and then use the sandblasting machine to perform sandblasting on the inner wall of the pipeline, so as to remove rust and other impurities on the inner wall of the pipeline. This method can only clean the horizontally placed pipeline. However, many existing pipes are installed vertically and are not easy to disassemble. Therefore, once the inner walls of these vertical pipes are rusted or bonded with other impurities, it will be difficult to clean the inside, thus affecting the normal use of the pipes.
